CORN-HUSKING ROLLS.

Specification of Letters Patent.

vPatented. Dec. '7, 1920.

Application sied January 14, isis. serial No. 211,794.

useful Improvements in Corn-Husking Rolls; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to Vcorn husking machines, and has particularreference tothe construction of the husking rolls.

The object of the invention is to provide an improved form of liuskingmechanism by a more etiicient arrangement of the liusking teeth orfingers with relation to the rolls, together with a practical mountingtherefor. By means of my improved construction, the teeth and theirmountings' may be manufactured at a minimum expense, and the teeth soinsertedtherein or secured thereto that they may be sharpened withoutremoving the mountings from the rolls,` Provision is also made, in theassemblage of the rolls to` prevent the breaking of the teeth when thedriving gears of the rolls accidentally become disarranged so as tocause the teeth to rotate in untimed relation.

With the above objects in view, and such others relating to the detailsof construction, as may hereinafter appear, my invention will now befullyv set forth and described,

reference being `had to the accompanying drawings. Y

ln the drawings VFigure l is a fragmentaryplan view of a pair of rolls,having the invention mounted thereon, p

Fig. 2 is a fragmentary perspective view of one of the rolls, l

Fig. 3 is an enlarged perspective view of one of the mountings withV itsassociated teeth,V Y I' Y Fig. 4 is a transverse section through therolls, and 'f Fig. is an enlarged 'section' through one of the tooth,Vmountings.

Referring more particularly to the drawings, l and 2 represent the rollsof a corn husking machine which are mounted in contiguous parallelrelation so as to close the bottom of an elongated hopper. The rolls iand2 Vmay be constructed of wood, metal or a combination of rtheseAmaterials in accordance with any particular-or desired method. Atregular intervals, the rolls l and 2 have cut'into their peripheralsurfaces the wide channels 4 and the narrow channels or grooves 5, thewide channel 4 and the groove 5 coming into closely spaced relation forthe purpose whichy will hereinafter appear, and, with relation to thejuxtaposed rolls, a narrow groove of one roll appearing opposite thewide channel 4 of the opposite roll.

. The channels 4 provide seatsfor annular bands, each made in aplurality of sections 6, and preferably in two semi-circular sections asshown, meeting end to end andheld within each channel removably byfastening' means such as the screws 7. The band as so constituted is asthick and as wide as the channel so that when in place its peripherycomplements that of the roll and, as

seen in-Fig. l, each channel is wider than the opposite groove'so thatthe band within it extends beyond both side walls of such groove. Thebandsections 6, in the form illustrated, are provided with Asocketshav-V ing spiral bottoms growing gradually deeper in the direction ofrotation of the rolls to their rear endsv 10 which are abrupt andradial. Each tooth 8 has a curved bottom resting on the bottom o f thesocket, a broad sharpcutting edge l2 undercut at its front end as at 13,and a receding back 14. The front end of the tooth is wholly beyond theperiphery of the roll as seen in Fig. 5, its rear end is wholly withinthe socket at the rear -end 10 of the latter, and its body between theseends is both curved and tapered from front to rear. The angles 12between the front ends and backs of the teeth are sharpened so as toprovide broad cutting edges which will take hold of the husks of thecorn deposited in the hopper, and tear them from the ears. When theperipheries of the iolls l and 2 roll one against the other, theoutstanding parts of the teeth on one roll operate in the groove 5 ofthe opposing roll; and in gearing the rolls toJ scribed, the teeth areso arranged that they will husk the corn thoroughly with a smallerpercentage of shelling of thekernels than isV mounted upon semiscircularVbands which may belsupplied ffor the renewal of the teeth upon` usedrolls, ,and lwhile the teeth are shown in the present instance asinserted into'th'e ibands, they may be otherwise se cured thereto orthey may be :formed as int-egaall elements.- ofthe bands.

`It is'well known that heretofore husking rolls fhave fbeen constructedwith pointed teeth on one roll'received in grooves in anotherroll,A andvin theroperation of the husking machine 4the teeth, by reason oftheirpointed lforination, penetrate the grains of cornnandicause'the grainsto be mutilated andpulled fromrthe cob. These teeth when entering thegrooves do not completely close? the :same Vonv opposite sides of theteeth, andthus the space becomes crowded with the eohs sand husks, andthe resultant pulling action of sa-iclhusks will cause the grains to beshelled, as Welllas clogging the husks in thefgro'oves `ofthe vrolls inthe machine when operated.

In the present invention, the teeth are formed with `loroad cuttingedges which eompletelycllose the grooves ente-red thereby, thusholdingthe ears out of said grooves and avoiding clogging by the-husks and atthek same time'preventing the teeth cutting through said v`husks andshelling the grain from said cob. The rolls hold back the ears,

chine.

It `will therefore be obvious that I have provided a. very simple andefiicient organization of parts for the husking rolls of corn huskingmachines.

lhat claim as my invention is z* l. Corn husking mechanism comprisingtwo rolls rotated oppositely and in contact and each having relativelynarrow annular grooves andrelatively wide annular channels respectivelyopposite like channels and grooves in fthe other roll, a band in eachchannel made upV of a plurality of sections of a thickness and Vwidth tofill the channel and to extend` beyond the edges of the groove in theopposite roll, means for securing said sections removably in place endto end, and teeth on each section extending beyond its periphery and ofa width to fill said groove.

2. Corn husking mechanism comprising two rolls rotated oppositely and inContact and each having annular channels opposite grooves in the other7semi-circular band sections removably secured in and filling eachchannel and having sockets whose bottoms grow deeper from front to rearin the direction of rotation and whose rear ends are abrupt and radial,and a tooth fitted in each socket with its front end extending V)eyondthe periphery of the roll and undercut, its cutting edge of the samewidth as the groove with which it coacts, and its back receding to itsrear end where it is flush withthe periphery of the roll. Y

In testimony whereof I aflix my signature in the presence oftwo'witnesses.
